ATTACHMENT FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent N 0. 770,870, datedSeptember 27, 1904.

Application filed em e 18, 1903. Serial No. 181,673. (No model.) i

To aZZ whom, it may concern:

Be it known that I, PHILEMoN LEE SLEEPER, a citizen of the UnitedStates, residing at Eakl y, in the county of Caddo and Territory ofOklahoma, have invented new and useful Improvements in Attachments forCultivators, of which the following is a specification.

This invention relates particularly to a weeder attachment forcultivators, and especially to wheeled straddle-row cultivators, and inaddition to its use as a weeder it may be used to excellent advantage toplow very young corn, cotton, or the like, where the ordinary shovelwould throw too much dirt.

The object of the invention is to produce an improved device of the kindstated characterized by novelty of construction and adjustment and bygreat utility-for purposes of tillage of crops grown in rows.

In the accompanying drawings, Figure l is a front elevation of part of astraddle-row cultivator with my invention applied thereto for use as aweeder. Fig. 2 is a perspective View showing the attachment adjusted asa plow, and Fig. 3 is a perspective of the attachment detached.

The device is intended to be attached to the beam of an ordinarystraddle-row cultivator, in substitution for one of the ordinarycultivator-teeth, which is removed for that purpose.

Referring specifically to the drawings, 6 indicates the axle of astraddle-row cultivator, and 7 the beams thereof. To the foot of one ofthese beams, preferably the inside one on each side, my device isattached.

The device has a shank 8, preferably of 00- tagonal form, so that it maybe securely bound in its clip 9 by a screw 10, the point of which bearsagainst one of the octagonal faces. It is obvious that the shank may bemade round or with various numbers of sides, the intent being to permitboth axial and lengthwise adjustment of the shank 8 in the clip toadjust the blade in or out or to turn it up or down. The blade isindicated at 11 and is fastened to one end of the shank, as by weldingor otherwise. Itis offset laterally or backwardly from the axial line ofthe shank and has its cutting edge'12 presented downwardly andforwardly.

It is slightly curved throughout the most of its length and at the rearend is bent up to a greater degree, as indicated at 13, at such aninclination as would substantially accord with the slope of the hillforming the row in which the crops are planted when the body of theblade is in its horizontal position, as shown in Fig. 1. The clip 9terminates in athreaded stem 9, which in use is placed in the slot 7 ofthe beam and there fixed by the nut 9 on the back side of the beam. Thispermits the clip 9, and consequently the blade, to be turned in the axisof the screw 9, so that the inclination of the blade may be varied toany degree between the horizontal and the perpendicular. When used as aweeder, the clip is so set that the blade extends in substantially ahorizontal position, and by reason of the rearward extension of theblade with respect to the shank the cutting edge 12 is presented at anangle to the line of draft and the tool is so set that the blade runsjust under the surface of the ground, when it will out oif or lift outthe weeds. The inclination of the blade may be adjusted in the axis ofthe shank to give the blade the proper or most efiicient out.

In use as a plow for very young plants, as indicated in Fig. 2, the clipis turned until the shank is in substantially a vertical position, inwhich case the main part ofthe blade will stand so as to cut verticallyinto the ground, and the curved end 13 will act to throw the earth tothe plants and hill up a slight ridge. In this use a lengthwiseadjustment of the shank 8 permits the blade to be run as deep' or asshallow as desired, while the axial adjustment of the shank permits therear end of the blade to be run as close to the row as desired.

It will be understood that in straddle-row work two of the attachmentsare used, one on each side; but the scope of the invention is notlimited to use with any particular cultivator nor otherwise than isindicated in the following claims.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a cultivator-beam having a slotted downturnedend, of a weeder attachment comprising a clip having a pivotcallyadjustable in the slot, a rotatable shank held by the clip andadjustable lengthwise therein, and a curved blade oifset backwardly fromthe shank.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PHILEMON LEE SLEEPER.
